p PLOW.

Crosse and State of ivisconsinfh avein vented certain new and useful Improvements in Plows, of which the followingisa full, clear, and exact description. I

The invention relates to plows and designs to provide improved and simple mechanism whereby the operator, byv foot action, may operate the plow to lower it and force it into the ground. r

The invention consists in the novel features hereinafter set forth and more particularly defined by claims at the conclusion hereof. i

In the drawings: Figure 1 isa side elevation of aplow, embodying the invention, the land-wheel and connected mechanism being omit-ted, and the mechanism for lowering the plow being shown in thefiposition assumed when the plow 1s in raised position. Fig. 2 is a similar view, parts being broken away, showlng the ,plow-lowerlng mechanism 1n posltion assumed whenthe plow is lowered. /Fig. 3 is'a plan, parts be 7 ing broken away. Fig- 4 is a section taken on line 44'of Flg. 1, on a la'rgerscale 10 denotesthe supporting frame sustained by the usual front furrow wheel 11, the.

rear furrow or, caster wheel 12 and the land-wheel 13 in any suitable -manner; as well understood in the art. A plow, 18:'is

secured to a beam 19 which isipivot-ally connected at its front to a crank -20;ona

shaft 21, which is journaled in suitable bearings 22 on the frame. The rear of the plow is controlled by a roller- 42 and guidebracket 40 having a cam slot '41 and seats 43 and 44 therein which cause the rear end of the plow to riseand fall in response to" rear, to a bracket 17 secured to'the frame,

and at its front, to a lug 17 on the plowbeam.

The improved plow operatingmechanism is applied to lower the plow and force it into the'ground, and comprises a foot-lever 24 which is fulcrumed, as at25, onthe crank '20, so that as the lever-fulcrum is shifted, crank 20 will beyshifted to lower the plow. The front end 2601? lever 24 is Specification of Letters Patent Application filed July 28,

adapted to engage a fixed 'stop pin 28 se- 30 which is secured to the frame by bolts 31.. Each of the teeth'is adapted to engage the stop-pm 28 to hold the lever against secure the crank 20 and the plow connected thereto, against downward movement. A roller .32. is oppositely disposed with'respect to the stop 28 and is journaled ina. forked plunger 33. This plunger is slidably ;mo'unted in a lug 34 on bracket and in a spring-housing 35, also formed on said. bracket. A stop-pin 36 limits the downward movement of the plunger inits guides, and a spring 37 in said housing enthe roller 32 in engagement with the front engagement with stop 28., The plunger 33 When the eratorplaces lhis foot upon the foot-piece 39 at the rear end of foot lever 24, initial 32 against. the forceof spring 37 until its movement] is iarrestediby proj ections 38 ene, gaging; the lug 34. The foot-lever will whichL-the leveris pivoted to be forced down,- wardly, while the front'end of the lever-is lever, as the crank 20 travels forwardly and downwardly, will ride on 'theroller and the as crank 20 is lowered, thus causing the .leverage to gradually increase as the plow approachejsthe ground, and so that as the plow curved and its lower side isprovided with serles of teeth ,or stops 27,;whichare" cured in a forkedextension 29 of a bracket 2 forward movement, so thatthe lever will gages the upper end of the plunger to hold' arm 2.6 of the foot-lever; Thus, the front,

portion of the lever is normally held between the fixed stop '28 and abutment 32, Y, and the latteryieldingly holds the lever: in

pressure will cause. the front end of the foot-lever to shift the abutment, and roller enters the.ground,- the lever will be work ratrnnir OFFICE,

is provided with projections 38 which areq adapted to engage the bracket lug 34;to positively arrest-the stop and hold it. in fixed rplation to the frame, when the rear end ofjthe foot-lever is depressed and the teeth 27 of thefOot-leverafre released from" plow lowering mechanisn1- is in the position shown in Fig. l and the ope 4 then be unlocked from the stop 28 and further'downward pressure upon the rear end I of foot-lever 24"will cause the crank20 on held against upward niov'ement by bear ing on the arrested abutment32' and the lever-fulcrum 25 will approach the roller,

It will be understood that any suitable.

ing on a short radius between roller 32 and the lever-fulcrum 25. Therefore, this simple mechanism serves to eifectivelylower the plow and provides eflicient and increased leverage at the time, when greater power is necessary to cause the plow to enter the soil. The sweep of the rear end of the foot lever is such that the plow may be conveniently operated.

mechanism may be employed for raising the plow, as well understood in the art, and since such mechanism forms no part of the present invention, it has not been deemed necessary to describe it in detail. hen the crank 20 is operated to raise the plow, the footlever will be restored to its normal position and if it is not desired to raise the plow, to the extent illustrated, the operation of the plow-lifting mechanism will be discontinued so that one of the teeth 27 will engage the lever and hold the plow in corresponding position.

The invention is not to be understood as restricted to the details shown and described, since these may be modified within the scope of the appended claims, without departing from the spirit and scope of the invention.

Having thus described the invention, what I claim as new and desire to secure by Letters Patent, is:
